Welcome to Sysnative!
I just ran the dumps again, I didn't see any new ones since the last time I ran them, a few days ago - have you had any new crashes? If not, perhaps the changes you've already made have had an impact?
What I immediately noticed this time was that there's no sign of a possible difference in win32k.sys - it looks like the MS Symbols server bugged on me the first time.
When you removed the graphics card, did you also remove the nVidia drivers? If not, please uninstall them now.
I'd appreciate another input here (Patrick?), note that only the last 4 dumps are from the current build/install,
Attached the files here, it's easier if they're all easily accessible: View attachment 5110
